Question: LED front directional lights for my 21975

[Tom DeMuth]

I replaced my OEM front directional light bulbs with LED bulbs, and I also replaced the flasher next to the fuse box under the dash. The LED's work great until you turn on the headlights. When you use the turn signal lever left or right the LED bulbs both light up and stay on, but they won't flash. Same thing happens when you turn on the Warning Flashers. All they will do is light up, but they will not flash. As soon as you turn off the headlights the LED directional lights and Warning Flashers work perfectly.
I like the LED lights because of their improved visibility and they draw fewer current. Does anyone have a solution?

Leds often need ballast resistors to be installed to get them to work properly for turn signals.
If the flasher you installed is for leds then you should be fine.
